POLE FITTING Filed June l7, 1935 INVENTOR ATTORNEY Patented Jan. 25, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to devices for supporting overhead electrical conductors on pole lines.

The present invention is a continuation in part to my co-pending application for Conductor sup- 5 port, Serial No. 1,707, filed January 14, 1935 which has matured into Patent No. 2,022,388 of November 26, 1935.

The principal object of this invention is the provision in a one-piece fitting of a combina- 10 tion conductor support and guy attachment.

The conductor support employed in this inven- In the drawing; Fig. 1 illustrates the fitting in the service position on a wood pole; Fig. 2 is a plan view of the fitting; Fig. 3 is a side elevational view; Fig. 4 is a sectional view of the 30 device along the plane IV-IV of Fig. 2; and Fig.

5 is an end elevational View of the fitting.

Referring in particular to Figs. 2, 3, 4, and 5, the shank I! is provided with threads at one end, and an integral base I2 at the other. As a desirable 35 but not essential modification, the shank may be squared adjacent the base I2, as indicated by the numeral IE, to retard rotation of the fitting about the axis of the shank Il. Integral with the base and extending outwardly therefrom is an upwardly turned hook portion comprising the stem I3 and the enlarged upper portion I I. The latter is provided with the horizontally disposed circumferential flange I4, and the wire-receiving groove I5, which extends across the top of the 45 enlarged upper portion I I in a direction substantially normal to the shank I'I.

Fig. 1 illustrates the device (here designated in its entirety by the numeral I0) installed on the pole 22, and held in place by the nut I8. The

guy wire 24 engages the upper convex surface of the stem l3, and has one end thereof secured in the usual manner by the clamp 25. The line conductor I9 extends across the wire-receiving groove I5, and the tie wire 20 cooperates with the flange M as required to provide a secure tie. To provide a tight tie, it is necessary that the bottom of the groove I5 be positioned at least not below the lower edge of the flange I4.

The numeral 23 indicates the device disclosed in 10 my above mentioned application, and is here shown only to illustrate the manner in which the present invention may cooperate with this or similar fittings, as by providing means for attaching the conductor 2| to the opposite side of the pole 22.

During the process of installation of a conductor on a pole line provided with the fitting described herein, the conductor may be laid upon the stem I3 and drawn thereover as it is pulled to final tension. The upper surface of the stem is convexly curved to assure that the conductor will not be damaged when this is done; also to provide a smoothly curving surface for engaging a guy wire where necessary.

The fitting herein described may be economically produced as a steel drop forging, or may be cast from some suitable metal.

ther embodiments of the invention may appear from the one specifically described and illustrated herein, but it is to be understood that my invention will be limited only by the appended claim and the prior art.

I claim as my invention:

A pole fitting for supporting an overhead conductor comprising in a single piece of metal a shank, a base portion at one end of said shank, an upwardly turned hook portion including a stem merging with said base at one end thereof and an enlarged end portion at the other end of said stem, said enlarged portion having a horizontally positioned peripheral flange extending outwardly from the upper portion of said enlarged end portion and a substantially semi-circular conductor-receiving groove extending transversely thereacross in a direction normal to the axis of said shank.
